Haihao Group has recently completed the delivery of a batch of high-specification blind flanges and figure 8 blind flanges for a valued customer in Russia, reinforcing our role as a trusted supplier of pipeline connection solutions for harsh environments.

RTJ A240 304 304L Figure-8 Blind Flange and A350 LF2 CL1 Blind Flange Produced By Haihao Group

One of the key products in this shipment is the 12″ ANSI 300 Blind Flange RF, manufactured in accordance with ASME B16.5. Made from A350 LF2 CL.1 carbon steel, this blind flange is designed for reliable sealing and end-of-line closure in medium to high-pressure pipelines. With excellent low-temperature toughness, it is particularly suitable for cold climate regions like Russia. Each flange is precisely machined, heat-treated, and protected with black coating and flange caps to prevent surface damage during transport.

The shipment also included 2″ ANSI 1500 Figure 8 Blind Flanges RTJ, crafted from A240 304/304L stainless steel. These figure 8 blinds, also known as spectacle blinds, feature a Ring Type Joint (RTJ) sealing face, ensuring secure sealing in high-pressure applications. The corrosion-resistant stainless steel construction makes them ideal for critical isolation and maintenance operations in aggressive media.

At Haihao Group, we pay attention to every manufacturing detail — from strict dimensional control and heat treatment to sealing face finishing and shipment protection. Our flanges are tested to meet both pressure and dimensional standards, giving clients confidence in every connection.

We continue to serve international markets with reliable products, timely delivery, and attentive service. If you are seeking high-performance blind flanges or figure 8 blinds that meet ASME B16.5 standards, Haihao Group is ready to support your projects.
